產品簡介

H型鋼(gang)(gang)的(de)(de)(de)(de)翼(yi)(yi)緣(yuan)內外(wai)側平行(xing)(xing)或接近于(yu)(yu)平行(xing)(xing)，翼(yi)(yi)緣(yuan)端(duan)部呈(cheng)直角，因此而(er)得名平行(xing)(xing)翼(yi)(yi)緣(yuan)工(gong)(gong)(gong)(gong)字(zi)鋼(gang)(gang)。H型鋼(gang)(gang)的(de)(de)(de)(de)腹(fu)(fu)板(ban)厚度比(bi)腹(fu)(fu)板(ban)同樣高的(de)(de)(de)(de)普(pu)通(tong)(tong)(tong)工(gong)(gong)(gong)(gong)字(zi)鋼(gang)(gang)小，翼(yi)(yi)緣(yuan)寬度比(bi)腹(fu)(fu)板(ban)同樣高的(de)(de)(de)(de)普(pu)通(tong)(tong)(tong)工(gong)(gong)(gong)(gong)字(zi)鋼(gang)(gang)大(da)，因此又得名寬緣(yuan)工(gong)(gong)(gong)(gong)字(zi)鋼(gang)(gang)。由形狀所決定，H型鋼(gang)(gang)的(de)(de)(de)(de)截面模數(shu)、慣性矩及相(xiang)應(ying)的(de)(de)(de)(de)強(qiang)度均明(ming)顯(xian)(xian)優于(yu)(yu)同樣單重(zhong)的(de)(de)(de)(de)普(pu)通(tong)(tong)(tong)工(gong)(gong)(gong)(gong)字(zi)鋼(gang)(gang)。用在不(bu)(bu)同要求的(de)(de)(de)(de)金(jin)屬結構(gou)中，不(bu)(bu)論是(shi)承(cheng)受彎曲力矩、壓力負荷、偏心(xin)負荷都(dou)顯(xian)(xian)示出它(ta)的(de)(de)(de)(de)優越性能，可較普(pu)通(tong)(tong)(tong)工(gong)(gong)(gong)(gong)字(zi)鋼(gang)(gang)大(da)大(da)提高承(cheng)載能力，節約(yue)金(jin)屬10%～40%。H型鋼(gang)(gang)的(de)(de)(de)(de)翼(yi)(yi)緣(yuan)寬、腹(fu)(fu)板(ban)薄、規格多、使用靈活，用于(yu)(yu)各(ge)種桁(heng)架結構(gou)中可節約(yue)金(jin)屬15%～20%。由于(yu)(yu)其翼(yi)(yi)緣(yuan)內外(wai)側平行(xing)(xing)，緣(yuan)端(duan)呈(cheng)直角，便于(yu)(yu)拼裝(zhuang)組合成各(ge)種構(gou)件，從(cong)而(er)可節約(yue)焊(han)接、鉚(liu)接工(gong)(gong)(gong)(gong)作(zuo)量25%左(zuo)右，能大(da)大(da)加(jia)快工(gong)(gong)(gong)(gong)程(cheng)的(de)(de)(de)(de)建設速(su)度，縮短工(gong)(gong)(gong)(gong)期。

用途

H型鋼廣泛(fan)應(ying)用于(yu)廠房建設、高(gao)層(ceng)建筑(zhu)、橋梁建設，石油鉆(zhan)井平臺等方面(mian)，發展鋼結(jie)構，創造和帶動(dong)了數以百計(ji)的(de)(de)新興產業(ye)的(de)(de)發展。
